When testing against NSS library, it seems that they only support the single part enc/dec PKCS11 APIs, so have to use a new class as existing P11Cipher class relies on the multi part enc/dec PKCS11 APIs and do not support key wrapping/unwrapping.

>From a high level, why does P11KeyWrapCipher support ENCRYPT and DECRYPT modes?  I expected to only see UNWRAP and WRAP mode supported.  Along those same lines I expected to only see C_WrapKey and C_UnwrapKey, and not encryption/decryption pkcs11 calls.  Is there some additional support here that I'm not seeing?
